One-Page Summary
Strange Case of Dr. Jekyll and Mr. Hyde begins with a respectable London doctor who creates a chemical formula that allows him to separate the opposing tendencies within his personality. As Dr. Henry Jekyll, he remains socially respectable; as Edward Hyde, he becomes free to indulge impulses he has learned to suppress. At first the arrangement seems useful. Jekyll can enjoy secret freedom while protecting his public reputation. But Hyde becomes increasingly powerful, and the distinction between the two identities begins to collapse. The lawyer Gabriel Utterson investigates the strange connection between Jekyll and Hyde after discovering that Jekyll has given Hyde unusual legal authority.
The story is deliberately mysterious because Stevenson withholds the explanation until late in the narrative. The horror is not simply that a man can transform into a monster. It is that the monster is not an outside invader. He is part of the same person. Jekyll’s experiment therefore becomes a metaphor for divided identity, repression, shame, temptation, and the dangerous fantasy that morality can be managed by separating “good” behavior from “bad” desire. The final confession reveals how quickly control can reverse into dependence. Hyde grows stronger because Jekyll repeatedly gives him permission to exist.
Stevenson’s novella remains powerful because it turns a Gothic mystery into a psychological question: if you could separate the parts of yourself you dislike, would you actually become better—or would you simply make it easier for those parts to act without restraint?
